The piston is movedby thepressure of water in one direction, which movement is transmitted to the cold-water-injection valve I will now describe my withreference to the accompanying drawings, in whic three-way cock.

This pipe usually contains a but in this invention I have represented simply a which may be understood as the injectionvalve or a simple cut-off valve? a? represents the outlet-pipe from the condenser carrying the waters of condensation and all the liquid GOHtBTLlStOf the condenser to the. hot well.

The thermometer extends back into the tube T, and is fitted with two contact-points projecting into the mercury column, one of theconductors being located at a :poin close the electric circuit and the other at some point below this.

The front stop '2" of this relay are in circuit with a main battery M B, which also includes an electro-magnet R, lever r one end of which is connected with a valve-stem r operatinga valve in chamber This valve controls three V mitting water under pressure from pip-e 11*, another connected with waste-pipe to, and the third leading to a cylinder W. The valve is constructed to either establish communication between the pipe and the cylinder \V, the waste-port being closed or else between the cylinder 1" and the waste-port w, the pipe 10 being cut ofi. The cylinder W contains a piston, which is adapted to reciprocate therein. Connected to the piston-rod is a weight X, to which is attached theend of a.

;My invention is not confined to a steamengine, but is obviously applicable to any machinery or apparatus where a condenser is used. For instance, it is well adapted for use in'the manufacture of sugar,'-dye-wood, extracts, and substances whereof light liquors are concentrated in vacuum-pans. Having thus described my. invention, I claim- -place -'that is, when t-hewatcr tlowin g through pipe a into the hot well D becomes too hotthermometer l) expands and makes metallic connection between the two contacts or terminals of the conductors 1 15 and closes the circuit through relay 1%, the armature-lever of wvhieh closes the second circuit through battery M 13 and magnet R, and the latter pulls up its armature and throws the valve in chamber 0' into such a position that cominunication will be established between cylinder W'and pipe iv. The pressure of water in cylinder W will then force the piston and the weight X. upward, allowing weighty to pull lever Y down and open to a greater extent the valve a supplying the cold water. When the supply of water is too great for thc'work .ot condensi'ngthe steam in the condenser, the lowering of' the temthe'cold-water supply perature in the. pipe o causes the thermonn trolled by said motor; eter to break the circuit and (lo-energize relay scribed.
